GYRATORY STRUCTURE.

Specification of Letters Patent.

Patented Dec. 2e, rent.

Application filed March 1, 1910. Serial No. 546,668.

To all whom it may concern Be it known that I, GEORGE WV. CoMBs, a citizen of the United States, residing at Leavenworth, in the county of Leavenworth and State of Kansas, have invented certain new and useful Improvements in Gyratory Structures, of which the following is a specification.

This invention relates to improvements in self-balancing gyratory structures, such as flour sifters, etc., and one of my objects is to support the structureshaft and parts afiixed thereto by antifrictional means independent of the structure, so that said shaft may be free to move laterally in any direction and the bearings of the structure relieved of the weight of the shaft and the parts carried thereby.

A. further object is to overcome excessive throw of the structure when starting or stopping, and also after said structure has attained normal speed, to the end that vibration may not be imparted to the building containing the structure.

Other objects of the invention will hereinafter appear, and in order that said invention may be fully understood, reference will now be made to the accompanying drawings, in which:

Figure 1 shows a gyratory structureprovided with my improvements. Fig. 2 is a horizontal section on line 11-11 of Fig. 1. Fig. 3 is an enlarged vertical section on line 111 of Fig. 1. Fig. 4: is a horizontal section on line IVIV of Fig. 3. Fig. 5 is a detail of an antifrictional supporting member, forming an important feature of the invention. Fig. 6 shows a modified form of the invention, and Fig. 7 is a horizontal section on line VII-VII of Fig. 6.

1 designates a sieve-structure or body freely supported for gyration by flexible rods 2, depending in the present instance from a ceiling 3. with centrally-disposed bearings 4, inwhich a vertically-positioned Shaft 5 is freely mounted inthe bearings 41 so that it will not be lifted from an antifrictional supporting member, hereinafter described, when the structure swings outward and upward into its gyratory course.

6 designates a pair of eccentric-weightsfixed to shaft 5 to assist the latter in imparting a gyratory motion to the structure when the shaft is rotated.

Structure 1 is provided shaft 5 is journaled.

, thereby.

7 designates an eccentric-pin secured to the lower end of shaft 5 a fixedly-mounted driver 8, which together with said pin is capable of orbital movement. a

9 designates an endless belt extending around a small pulley 10 and a small pulley 11, fixed 'to vertical stub-shafts 12 and 13, journaled in bearings 11 and 15, respectively. Shaft13 is provided with a bevel gear wheel 16 driven by a bevel gear wheel 17 fixed upon a driven shaft 18, mounted in bearing 15. Bearings 14 and 15 are adjustably mounted upon bed-plates 18 and 19, provided with screws 20 and 21, respectively, whereby said bearings may be adj usted either toward or away from each other for the purpose of tensioning belt 9, whereby pulley 8 is driven, and the structure restrained from abnormal throw while in operation. Bearings 14 and 15 are also laterally-adjustable upon the bed-plates 18 and 19, which are provided with set-screws 21 and 22*, respectively, for efl'ecting said lateral adjustment.

22 designates the antifrictional supporting member, above referred to,which carries the weight of the shaft and the parts aflixed thereto independently of the structure 1, and thereby relieves the bearings of the latter of the wear and strain which would result from carrying the shaft and the eccentric weights. Member 22 is supported at its lower end in a step-bearing 23, and normally extends in axial alinement with eccentric-pin 7, which rests thereon, as shown in Fig. 3, a hardened steel button 24: being interposed between the upper end of the antifrictional member and the lower end of the eccentric-pin to protect the latter from wear. The lower portion 25 of member 22 is of spherical form, and is seated within a socket-member 26 within the step-bearing so that said member 22'may oscillate freely in any direction, should eccentrio-pin 7 move laterally, or so that the upper portion of said member 22 may move orbitally with the pin, should the structure leave its true gyratory course. The upper portion of member 22 is provided with a circular head 27 having a convex upper surface 28, so that it will have a rolling contact with the lower end of the eccentric-pin 7 ,carried The curvature of the covex upper surface 28 of member 22 is such that the eccentric-pin 7 will be maintained on, substanand provided with a I tially,"lthe same horizontalplanej notwithrelation to each other an--upwardly-extending hub 30, loosely-embracing the lowerportion of the eccentricpin, and adepending boss 31 embracing the upper portion of member 22, as shown in j; IjfiFig; f Boss 31 is protected from Wear-by a hardened steel annulus 32,
